# Quad 4090 48Gb 768Gb Ddr5 In Jonsbo N5 Case: A Comprehensive Guide for High-Performance Homelab Setup

In this guide, we will delve into the intricacies of setting up a high-performance workstation featuring Quad 4090 GPUs, 768Gb DDR5 memory, and the Jonsbo N5 case. This setup is ideal for homelab environments, self-hosted applications, and resource-intensive development tasks.

Prerequisites

• Operating System: Ubuntu Server 20.04 LTS or higher
• Hardware Specs: Intel 6530 32 Cores Emerald Rapids CPU (or equivalent)
• Software: NVIDIA Driver version 470.XX (replace XX with the latest stable version) and CUDA Toolkit version 11.XX (replace XX with the latest stable version)
• Network Requirements: Stable internet connection, static IP address, and firewall rules allowing traffic to necessary services
• User Permissions: Root access or sudo privileges for installation and configuration tasks

Installation & Setup

1. Install Ubuntu Server: Follow the official Ubuntu Server installation guide.

2. Update the system: Run sudo apt update && sudo apt upgrade -y to ensure your system is up-to-date.

3. Install NVIDIA Driver and CUDA Toolkit: Follow the official guide for installing NVIDIA Driver and CUDA Toolkit on Ubuntu Server.

4. Verify Installation: Run nvidia-smi to confirm the driver installation and check the GPU details.

Configuration

1. Configure CUDA Toolkit: Edit the ~/.bashrc file and add the following lines:

    export CUDA_HOME=/usr/local/cuda-11.0
    export PATH=$CUDA_HOME/bin${PATH:+:${PATH}}
    export LD_LIBRARY_PATH=$CUDA_HOME/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
   

2. Security Hardening: Implement best practices such as hardening SSH, limiting failed login attempts, and updating your system regularly.

3. Performance Optimization: Adjust the BIOS settings for optimal performance, considering factors like memory timings, fan speeds, and voltage control (if applicable).

4. Integration with Other Services: Install and configure Docker or Kubernetes for containerization and orchestration tasks.

Usage & Operations

• Common Commands: nvidia-smi, docker run, kubectl apply
• Monitoring: Use tools like Grafana for monitoring system performance and GPU utilization.
• Backup & Recovery: Regularly backup your data using solutions such as rsnapshot or BorgBackup.
• Scaling: If needed, consider adding more GPUs to the system and scaling storage accordingly.

Troubleshooting

• Common Issues: GPU driver conflicts, memory leaks, and performance bottlenecks
• Debug Commands: nvidia-bugreport.sh, docker logs <container_id>, kubectl logs <pod_name>
• Performance Tuning: Adjust the number of GPU cores assigned to each container, use cgroup v2 for better resource isolation, and optimize application code for parallel processing.
